The heat exchanger is adapted for cooling a coolant (e.g., water), used to cool a device or an area (e.g., building interior), such as during periods of peak energy cost and usage, to save energy and energy costs. The heat exchanger includes a coolant storage tank with one or more refrigerant circulators in contact with the floor of the tank. The circulators use a refrigerant having a freezing temperature colder than the coolant, with coolant on the floor of the tank forming a layer of ice thereon. A rotary scraper extends up through the tank floor from each circulator, with the scrapers operating to remove the thin layer of ice from the floor as the ice forms. The resulting ice chips are relatively small and thin, thus having a relatively large surface area for their volume in order to maximize melting and rapid cooling of the coolant.

A system for producing heat-sink assemblies in which a series of extruded members possess mating faces, each face having an alternating series of troughs and bulbous shaped ridges which are formed from the sides of the troughs. Mating ridges of one face of each extruded member are dipped with a thermally conductive compound prior to press-fitting and at least some of the ridges and troughs possess a groove that when mated to an opposing region of an adjacent extruded member, produces a reservoir that serves as a feeder source for thermally conductive compound.
